What restaurant symbol did McDonald’s turn into its famous yellow M-shaped logo?

McDonald’s turned the Golden Arches into its famous yellow M-shaped logo.

The arches began as large structural features on McDonald’s restaurant buildings during the 1950s. Their purpose was practical as well as visual: the bright, curved forms made the restaurants easier for passing motorists to recognize. Over time, the architectural elements became a standalone emblem.

The two arches were eventually combined into the letter-like M associated with McDonald’s. This was a major branding shift because customers could recognize the company even when the full name was absent. The symbol became especially powerful on roadside signs, packaging, uniforms, and advertising.

The Golden Arches are sometimes described as simply a stylized letter M, but their origin was architectural. That history distinguishes them from later graphic logos created solely for printed materials. Their durability comes from the way the logo connects McDonald’s visual identity with its early restaurant design.
